App takes user options and creates an array objects randomly, and based on user options. (it's a gamer tag generator, writing to learn react.js). As is, App is a functional component and I use useState to store array of objects (gamertags) and the current selected options.

I use formik for my simple form. It takes two clicks to get a new item with updated options. I know why, options in state of App doesn't not update until it rerenders as the function for form submission is async. Therefore, all of my options are updated, after the first click, and are correct with the second because they were updated with the rerendering and after I needed them.

I know the solution is to use a useEffect hook, but despite reading over other posts and tuts, I don't understand how to apply it. It's my first instance of needing that hook and I'm still learning.

I wrote a simplified App to isolate the problem as much as possible and debug. https://codesandbox.io/s/morning-waterfall-impg3?file=/src/App.js

I've implemented a Wishlist functionality on a site, heavily based on this tutorial Tuts Plus Create AJAX Wishlist Plugin. It's working as expected, apart from the stock output from the Rest API call - it returns "instock" or "outofstock" and I'm banging my head against a brick wall trying to work out how to get it to return a formatted string (e.g. "In stock!" wrapped in a span) instead. I spent most of yesterday trying to format it in any way I know how with no success.

Here are the relevant parts of the code in the plugin PHP file:

I have trying to make some "replacement-wrapper" over stream described in this : [article][1]

But when I tested it with not so big file (about 120M) it showed me an error:

So I've read the formik docs, and a dozen tuts and examples and I don't understand the most concept of formik and forms.

I am generating random gamer tags, then letting the user rate and organize them. this is all to help me learn react. I need to know which options they want from a list of radio and checkboxes. So I'd love to know in the state of my app (top level), which options the user has picked. Here is an outline of how my app is structured.

I am trying to check if the user is in the index.html and I have this code down.

I'm working on my first MERN stack project, and I don't understand JWT, I've watched many tuts and I get the concept, but when it comes to realization I just can't do it. :/

So, I have a couple of routes here. I made controllers for them The last one (user) is supposed to be protected

I've looked through the documentation. I've scoured YT for tuts and googled to no avail. Maybe this is just beyond the scope of MUI, but it seems really counter-productive.

I'm just looking for a non-hacky, semantically-correct way of having my color palette defined where components can access the different colors (I know the color prop needs a wrapper, but even a style with the color var is ok to me for this).

My color object is as follows:

I'm trying to make a context menu and I saw some tuts in which they program the next code for example:

I have found some great tuts on how to make a flip card with CSS. My question though is how to make this keyboard accessible. In other words, for a user with a disability who only is using a keyboard, hopefully they would be able to just use the tab button (thus focus), and the card would turn over to show the back content and allow tabbing to select links on the card's back.

I Googled this and found some suggestions (please see the jsfiddle below where I tried them), but I couldn't get success.

Here is a great website that has this functionality, but I don't know how they made it work: https://businessexpress.maryland.gov/

Notice that if you hold tab down on the above page, eventually your cards will flip, and you can then tab through the links on them. For example, for the first flip card there is a link "/plan", and then it has sublinks like "/plan/create-business-plan", etc.

Please notice that I tried to put in some CSS on line 21 that would affect the "active" and "focus" pseudo classes. But only hovering makes the card flip. I wish that tabbing onto any of the links would flip the card, like in the maryland.gov example above.

I've included a jsfiddle here (there is a little input element so you can start tabbing from it): https://jsfiddle.net/anrbhcmv/
